SADDLE FOR BICYCLES.

SPECIFICATION forming part of Letters Patent No. 647,215, dated April10, 1900?.

Application filed December 4, 1899. Serial No. 789,081. (No model.)

To all whom it may concern:

Be it known that we, PATRICK BRODIE and ROBERT P. BLAKE, of Boston,Suffolk county, Massachusetts, have invented a new and useful ImprovedSaddle for Bicycles and the Like, of which the followingis aspecification, reference being bad to the accompanying drawings, inwhich Figure 1 is a plan view of our saddle, and Fig. 2 is a sectionalelevation on line 2 2 of Fig. 1. Fig. 3 is a section on line 3 3 of Fig.1 looking in the direction of the arrow.

The object of our invention is to'provide a seat in which no pressurewill be possible upon any portion of the riders person where suchpressure is undesirable either for reasons of comfort or health, and tothis end we provide a saddle made up of two separate portions mountedupon the supporting-spring independently of each other and eachperforming distinct functions.

In the drawings the supportingspring,

which serves not only as a spring to give elastioity to the saddle andto take up and neutralize the jars passed from the roadway through thewheels, but also to support and maintain the two parts of the saddle intheir operative relations, is marked A. The spring A is secured to thevehicle in the ordinary well-known manner, as is indicated in Fig. 2, bya clamp a, connecting the spring with the saddle-post of a bicycle. Thespring A can be moved longitudinally through the clamp in the well-knownway,'and by reason of its curve the saddle may be tilted to the requiredangle.

Fast to the rear end a of the spring A is a metallic frame B ofsubstantially the shape shown in the drawings-that is to say, a narrowplate secured upon the rear end of the spring, at right angles thereto,and curving forward until the two horns or ends (7 of the frame areopposed to one another at a distance of about an inch and a half. Theedges of the horns Z) are rolled over slightly in order to form aneasier seat, and it will be obvious that the entire frame being fastonly at the back will have its full elasticity and resilience, dependingas to this upon the nature and temper of the metal of which the frame isformed.

The dimensions of the central aperture of the frame B are an importantpart of our device, for it is our design to support the weight of therider not upon the tuberosities of the ischii-that is to say, the bonyprojections but to allow these to be carried over the apertu re, whilethe frame B, suitably upholstered, if desired, shall receive and sustainthe load, thus giving a greatly-extended bearing-surface and doing awaycorrespondingly with the saddle soreness which follows the concentration of weight and shock upon a relatively-small surface.

\Ve have found in practice that a suitable size for the central apertureis about six inches in length by two and one-half inches in width, thewidth being the dimension which corresponds with the length ofthebicycle; but it is obvious that these dimensions will and may be variedto suit the individual for whom the saddle isintended. Thus, forexample, the dimensions would be considerably less in the case of asaddle intended for a child.

To the forward end of the spring A is pivoted neck D, which projectsbackward toward the main part of the saddle and is designed to serve thepurposes of similar parts in other saddles-that is to say, to give therider a hold against being thrown off sidewise. The form and mechanicalconnection and organization of parts of this neck D, so far as we areaware, are absolutely new with us. Its salient peculiarities are threein numberfirst, it is wider than is customary and is forked; second, itis supported from its front end, that end projecting toward the mainbody of the saddle being unsupported and unconnected directly with thebody of the saddle, and, third, it is so connected to the forward end ofthe spring A by means of a pivot as to be capable of such axial movementas is desired. The pivot-pin is marked a and the clasping part d. Thisneck D is preferably so formed as to slope from the rear end toward thefront, as shown in Fig. 2, so thatin case the rider slips or is thrownforward'there is no possibility of inj urious contact between the neckand the person of the rider. I

The mode of operation is as follows: The rider is seated centrally overthe aperture of the saddle proper formed by plate B,the tuberosities ofthe ischii or bony projections being unsupported-that is to say, restingwithin the oval aperture formed by the plate B. It

will be observed that the space between the horns I) b is sufficient toremove any danger of pressure upon delicate organs, while the length ofplate B from point b to the point of attachment to the spring A is suchthat the.

What we claim is-- In a saddle the combination of a supporting"- spring;frame-plate B secured at the rear end of said spring and curving aroundto the points I) b suitably separated from each other, and a forked neckD mounted upon the supporting-spring at its forward end and project ingbackward to cooperate with the seat part of the saddle, substantially asdescribed.
